Specification of Letters Patent.

Patented May 10,1921.

Application filed October 31, 1919. Serial No. 334,807.

T 0 all whom it may concern:

Be it known that I, RICHARD G. LEDIG, a citizen of the United States, residin in the city and county of Philadelphia, gtate of Pennsylvania, have invented a new and useful Guard for Electric Heaters, of'which the following is a specification.

My invention consists of a guard for an electric or other heater and consists of a wire or open work front body, and a rear heat receiver and deflector, said front body being of an expansible nature and adapted to be contracted and thereby fitted to the rear bodyand retained in position thereon by its subsequent expansion.

The invention is satisfactorily illustrated in the accompanying drawing but the important irrstrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a front view partly broken away of an electric heater guard embodying my invention.

Fig. 2 represents a diametrical section thereof on line 2-2 Fig. 1, some of the wires being fore-shortened.

Fig. 3 represents a' front view of a portion of the front body in normal condition.

Fig. 4 represents a diametrical section of a portion of the rear member on an enlarged scale.

1 designates a series of wires which are 1 clamped in front to the annulus 2 and connected at the rear with the ring 8 by riveting or other means forming together the convex body 1 which per se is known in the art. The annulus or rlng 2 which gathers the front of the wires or arms 1 at the center of the guard and firmly sustains the same thereat allows by its open nature the radiation of heat without obstruction through the same, the heat radiating also through the spaces between said arms.

The ring 3 is divided or parted as shown in Fig. 3, whereby said body is expansibly and contractibly resilient. 5 designates the concave body of sheet metal or other suitable material in which an electric heater, not shown, is contained, said body having on its peripheral portion 6 the channeled rim 7 whose front wall 8 is inturned toward the center of said body 5 and open in front so that the ring 3 may be passed under said wall 8 and seated in the channel of said rim and so be held in position by the latter. The

body 5 forms a member for receiving heat and deflecting it therefrom through the wire or open-work body 4:.

It will be seen that the wire body 4: in normal condition is expanded as shown in big. 3 whereby its diameter is greater than the diameter. of the rim 7 of the body 5.

N ow in order to fit said body 1,011 the body 5 and connect it therewith the terminals 9 of the divided ring 3 are brought together, the wires 1 closing toward each other and so the ring 3 is of less diameter than that of the front wall 8 of the rim 7. The ring can now be passed under said front wall 8 of the rim and seated in the channel of the latter which being done and the ring let go said ring expands in the channel of the rim 7 and so is seated in the latter and prevented from outward forward displacement therefrom by the front wall 8 of the rim, the rear wall of the channel of the rim preventing rear displacement of said ring and so the ring is connected with the rim,

' whereby the two bodies 1 and 5 are held in engagement, and so interlocked.

It is evident that by contracting the diameter of the mug by bringing its terminals together said ring may be drawn out under 7 the front wall of the rim 7 and the body 1 removed from the body 5 for any purpose re uiring the same.

aving thus described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a guard for an electric heater, a series of arms, and an annulus adapted to support said arms at the center of the front of the guard, said annulus being of open form.

2. In a guard for an electric heater, a

series of arms, an annulus supporting said arms at the center of the front of the guard, and an annulus of open form secured to said arms near the extremities thereof.

3. In a guard for an electric heater, a series of arms, and an annulus supporting said arms at the center of the front of the guard, said annulus. being adapted to have said arms secured thereto.
